# The side of the square is 18 cm. The perimeter of the rectangle is equal to the perimeter of the square.

The side of the square is 18 cm. The perimeter of the rectangle is equal to the perimeter of the square. The length of the rectangle is 1/2 of its width, and the width is 24 cm. How many square centimeters is the area of the square larger than the area of the rectangle?

1. Calculate the length of the second side of the rectangle:

24 x 1/2 = 12 centimeters.

2. We calculate the perimeter (P) of the square, taking into account that all sides of this geometric figure

are equal:

18 x 4 = 72 centimeters.

3. Calculate the area (S) of the square:

S = 18 x 18 = 324 centimeters².

4. Calculate the area (S) of the rectangle:

12 x 24 = 288 centimeters².

5. Calculate the difference between the areas of a square and a rectangle:

324 – 288 = 36 centimeters².

Answer: the difference between the areas of a square and a rectangle is 36 centimeters².
